I am getting an error when using topojson saying that the command cannot be found. I think the install has gone OK but there just isn't a command for topojson, but there are ones for topo2geo, topomerge etc. I'm using nvm if that is relevant and on mac.

Some Node details:

topojson is there, but...

No topojson here??

My path, which is saying something about a valid identifier. Is this an issue?

    Grahams-MacBook-Air:data grahamfletcher$ export $PATH
-bash: export: `/Library/Frameworks/GDAL.framework/Programs:/opt/local/bin:/opt/local/sbin:/Users/grahamfletcher/.nvm/versions/node/v7.10.0/bin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/local/bin:/usr/local/share/dotnet:/Library/Frameworks/Mono.framework/Versions/Current/Commands': not a valid identifier

  • It looks like topojson has installed correctly. Have you tried running your node project? – Thomas5631 Nov 23 '17 at 20:34
  • I've installed globally so I can use topojson from the command line. When I enter the command topojson in the terminal it says the command cannot be found. Topomerge etc work and ogr2ogr work. Just can't see why topojson doesn't! – Graham Fletcher Nov 24 '17 at 10:27
  • I thin from the link https://medium.com/@aendrew/creating-topojson-using-d3-v4-10838d1a9538 it is mentioned that "Note also that topojson/topojson is no longer the command-line tools for manipulating TopoJSON — that’s all been put in the topojson/topojson-client repository."You would need to read the reference page "https://github.com/topojson/topojson-client/blob/master/README.md". to find usable command. – smile Dec 13 '17 at 04:39
